如何将Curl请求参数转换为VLC命令下载需登录视频

背景 #

我已熟练掌握通过VLC的「Open network stream」图形界面下载视频的方法，成功操作过数十次，仅曾需添加http-referrer参数，其余情况均正常。现在想下载一个需要登录权限的视频（我拥有合法访问权限，仅截取片段），但VLC返回HTTP 403错误。

错误信息 #

access error: HTTP 403 error

http error: local stream 1 error: Cancellation (0x8)

验证可行性：成功的Curl命令 #

我已用Curl携带必要Cookie和请求头成功下载包含*.ts文件的播放列表，命令如下：

curl 'https://video-course.coolsite.com/video.m3u8' \
  -H 'authority: video-course.coolsite.com' \
  -H 'accept: */*' \
  -H 'accept-language: en-US,en;q=0.9,de;q=0.8' \
  -H 'cache-control: no-cache' \
  -H 'cookie: CloudFront-Key-Pair-Id=ABCDEF; cf_clearance=LONGSTRINGCONTINUES; FUP_vid=12345; etc.' \
  -H 'dnt: 1' \
  -H 'origin: https://www.coolsite.com' \
  -H 'pragma: no-cache' \
  -H 'referer: https://www.coolsite.com/' \
  -H 'sec-ch-ua: "Chromium";v="118", etc.' \
  -H 'sec-ch-ua-mobile: ?0' \
  -H 'sec-ch-ua-platform: "Linux"' \
  -H 'sec-fetch-dest: empty' \
  -H 'sec-fetch-mode: cors' \
  -H 'sec-fetch-site: same-site' \
  -H 'user-agent: Mozilla/5.0 etc.' \
  --compressed

尝试的VLC命令框架（未完成） #

我尝试过GUI和vlc/cvlc命令行的多种参数（如:cookie='…'、:set-cookie='…'等），但不清楚VLC对应参数的名称，也不确定是否能与Curl参数一一对应，目前的命令框架如下：

cvlc 'https://video-course.coolsite.com/video.m3u8' \
   :???='video-course.coolsite.com' (authority) \
   :???='*/*' (accept) \
   :???='en-US,en;q=0.9,de;q=0.8' (accept-language) \
   :???='no-cache' (cache-control) \
   :???='CloudFront-Key-Pair-Id=ABCDEF; cf_clearance=LONGSTRINGCONTINUES; FUP_vid=12345; etc.' (cookie) \
   :???=1 (dnt) \
   :???='https://www.coolsite.com' (origin) \
   :???='no-cache' (pragma) \
  :http-referrer='https://www.coolsite.com/' \
   :???='"Chromium";v="118", etc.' (sec-ch-ua) \
   :???='?0' (sec-ch-ua-mobile) \
   :???='"Linux"' (sec-ch-ua-platform) \
   :???='empty' (sec-fetch-dest) \
   :???='cors' (sec-fetch-mode) \
   :???='same-site' (sec-fetch-site) \
  :http-user-agent='Mozilla/5.0 etc.'

需要将上述Curl请求参数转换为有效的VLC参数，解决HTTP 403错误并成功下载视频。
